Resumen de Radio flashes may be noise of black hole births
Mysterious radio bursts from the distant cosmos are revealing their true nature. They may be the death cries of a collapsing neutron star being severed from its magnetic field as it turns into a black hole. In 2007, the first fast radio burst (FRB) was detected. Blinking stars called pulsars emit periodic radio flashes, but this event seemed much farther away than any known pulsars, suggesting immense power. Since then, only one more FRB had been seen. Now Dan Thornton of the University of Manchester, UK, and colleagues have discovered four more using a telescope in Parkes, Australia.
